BLUEY, BLE DEVELOPMENT BOARD SUPPORTS NFC

are assistant tools that help engineers andΒ enthusiasts to become familiarized with hardware development. They simplify the process of controlling and programming hardware,Β such as microcontrollers and microprocessors.

Electronut Labs, an embedded systems consulting company, had produced its newΒ BLEdevelopment board β€œBluey” with a set of useful sensors and NFC support.

Bluey isΒ an open source board that featuresΒ theΒ Nordic nRF52832 SoCΒ which supportsΒ BLE and other proprietary wireless protocols. Bluey has built-in sensors that include temperature, humidity, ambient light and accelerometer sensors. Also, it supports NFC and comes with a built-in NFC PCB antenna.

The nRF52832 SoC is a powerful, ultra-low power multiprotocol SoC suited forΒ Bluetooth Low Energy,Β ANTΒ and 2.4GHz ultra low-power wireless applications. It is built around a 32-bitΒ ARM Cortexβ„’-M4F CPUΒ with 512kB + 64kB RAM.

Bluey Specifications:

  • Nordic nRF52832 QFAA BLE SoC (512k Flash / 64k RAM)
  • TI HDC1010 Temperature/Humidity sensor
  • APDS-9300-020 ambient light sensor
  • ST Micro LSM6DS3 accelerometer
  • CREE RGB LED
  • CP2104 USB interface
  • 2 push buttons
  • Coin cell holder
  • Micro SD slot
  • 2.4 GHz PCB antenna
  • NFC PCB antenna

Bluey can be programmed usingΒ theΒ Nordic nRF5 SDK. You can upload the code with an external programmer such as theΒ Nordic nRF52-DK, or theΒ Black Magic Probe firmwareΒ onΒ STM32F103Β breakout. But, within the built-inΒ OTA (over the air)Β bootloader, you canΒ upload the codeΒ directly using a PC or a phone.

The sensors on the board require a minimum of 2.7 volts to function properly, and theΒ maximum power is 6 volts. Bluey’s design offers three different ways to power it, all of them have aΒ polarity protection:

  1. Using the 5V micro USB connector (which also gives you the option to print debug messages via UART).
  2. The + / – power supply pins which can take regular 2.54 mm header pins, a JST connector for a 3.7 V LiPo battery, or a 3.5 mm terminal block.
  3. A CR2032 coin cell for low power applications.
  4. You can use Bluey for a wide range of projects. The BLE part is ideal for IoT projects, or if you want to control something with your phone. The nRF52832 SoC has a powerful ARM Cortex-M4F CPU, so you can use this board for general purpose microcontroller projects as well.

Bluey is available for $29 for international customers fromΒ Tindie store. Indian customers can purchase it fromΒ Instamojo store. There are also discounts for bulk purchases. For more information about the board visit itsΒ github repository, where you will find a full guide to start andΒ a bunch of demo projects.
